Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed August 24, 1903. Serial No. 170,658.

To ztZZ 1077,0727 it ntay concern;

Be it known that I, GEORGE N IOHOLAS SoEETs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Journal-Bearings, of which the following is a specification.

This invention relates to car-journal bearings; and it consists particularly of certain novel improvements on the bearingcovered by Letters Patent No. 705,871, dated July 29, 1902.

The object of this invention is to provide additional stops on the wedge to limit the movement of the brass and produce a larger hearing surface for the different kinds of brasses.

The invention has other objects in view, which will fully appear in. the detailed description thereof.

In the accompanying drawings, Figures 1, 4, 7, and are plan views of wedges, showing diflerent embodiments of the invention. Figs. 2, 5, 8, and 11 show the corresponding brasses for said wedges. Fig. 3 is a longitudinal sectional view on the line 3 3 of Fig. 2 Fig. 6 is a transverse sectional view on the line 6 6 of Fig. 5. F ig. 9is a longitudinal sectional view on the line 9 9 of Fig. 8. Fig. 12 is a transverse sectional view on the'line 12 12 of Fig. 11.

In the drawings I have shown several embodiments of the invention, and, referring thereto,20,20, ,and 20 designatebrasses which are provided with raised crowns 21, 21, 21, and 21, and 22, 22, 22, and 22 are wedges or keys for securing the brasses in place. The wedges are provided on their under sides with recesses 23, 23; 23, and 23 to receive the crowns on the brasses, and these recesses are somewhat larger both in length and width than their respective crowns, so that the brasses may have more or less movement relative to the wedges.

The crown and recess may be variously shaped, and in the drawings'I have shown several different forms, in each of which the crown is indented at its edge, and the wedge is provided with stops in addition to the walls of the recess to engage the crown and limit the movement of the brass.

In Figs. 1 to 3 the stops are formed by inward projections 24 at the end walls 25 of the recess, and the crown on the brass is recessed or cut out at 26 to accommodate said proj ections. In this construction the movement of the brass relative to the wedge is limited by the engagement of the indented end of the crown with the end wall of the recess and the projections forming the stop.

The stops may be formed by ribs variously arranged, and in Figs. 4 to 9 I have shown two constructions of this character. In Figs. 4 to 6 the ribs 27 are arranged diagonally of the wedge and meet each other about the center of the recess, and the crown is provided with channels 28, arranged in a manner corresponding to the ribs 27 and adapted to re ceive the same. In Figs. 7 to 9 the ribs 29 are arranged transversely of the wedge and the brass has its crown divided into sections 30, which are separated from each other to provide channels 31 to receive the ribs. these constructions the ribs on the wedge, which are adapted to be engaged by the walls of the channels in the crown, constitute the stops intermediate of the ends of the recess to cooperate with the end walls of the recess for the purpose of limiting the movement of the brass.

In Figs- 10 to 12 the recess in the wedge is provided with offsets 32 in its side walls to accommodate projections 33 on the crown, and both the recess and the crown are formed narrower on both sides of said ofisets and projections than at their ends. In this construction the walls of the offsets constitute the stops. p

The crown may be of greater height than the depth of the recess, so that it will support the wedge and the weight carried thereby in the manner shown in Figs. 3, 6, and 9; but, if desired, the parts may be so constructed that the wedge will rest upon the crown, whatever may be its construction, and also upon the faces 34 of the brass, as shown in Fig. 12. The projections 24 of Fig. 1, the ribs 27 and 29 of Figs. 4 and 7, and the inward projections 35 of Fig. 10 constitute additional bearing-surfaces on the wedges to engage the complementary brasses herein shown and described or the Master Oar-Buildersstandard brass. The wedge is provided with depending sides 36 with inclined inner faces 37, and the brass has inclined sides 38, complementary to the inclined faces 37. of the wedge, so that the wedge and the brass may be used interchangeably with the Master Oar-Builders wedge and brass, Figs. 4 and 6. The brasses are also somewhat reduced in weight by the indentations and channels in the crown.

Without limiting myself to the particular construction and embodiment of the invention illustrated in the drawings, what I claim as new, and desire to secure by Letters Patent, is

1. A carjournal bearing comprising a wedge provided with a recess having straight walls, and a brass provided with a raised crown having straight walls to work in said recess, said brass and. wedge being relatively movable in parallel planes and said wedge being provided with stops to engage the crown intermediate of its ends and limit the movement of the brass. I

2. A car-journal bearing comprising a wedge having a recess in its under side, a

20 brass provided on its top with a raised crown to work in said recess, said wedge having projections extending into the recess from its surrounding walls, and said crown being shaped to receive said projections.

3. A car journal bearing comprising a wedge having a recess in its under side, a brass provided on its top with a raised crown to work in said recess, ribs in said recess, and channels in the crown to receive said ribs.

4. A car ournal bearing comprising a wedge having a recess in its under side, a brass provided on its top with a raised crown to work in said recess, crossed ribs in said recess, and channels in the crown complementary to said ribs.
